Catriona Halliday is the Principal Scientist in charge of the Clinical Mycology Reference Laboratory, at the Institute for Clinical Pathology and Medical Research (ICPMR), NSW Health Pathology based at Westmead Hospital in Sydney. The laboratory has partnerships with Centre for Infectious Disease - Public Health (CIDM-PH) and the Sydney Institute for Infectious Diseases at the University of Sydney. Catriona is actively involved in teaching both scientific and medical staff in medical mycology and her research interests have focused on the development and implementation of culture independent tests to aid in the rapid diagnosis of invasive fungal infections, in particular invasive aspergillosis. More recent research projects have involved the evaluation of antifungal susceptibilities of novel antifungal drugs and the use of whole genome sequencing to detect antifungal resistance. She is head of the Laboratory Working Group of the Australian and New Zealand Mycoses Interest Group (ANZMIG), and a founding member of the ISHAM working group for Fungal PCR (FPCRI) working with international colleagues to develop recommendations to optimize PCR testing in fungal diagnostics. Most recently, Catriona is a member of the multi-disciplinary team of researchers who were awarded funding from WHO to develop the Fungal Priority Pathogen List and describe the R&D antifungal and diagnostic pipeline.
